A more stable ride starts with your suspension. This anti-sway bar kit helps reduce body roll and keeps your vehicle feeling more planted through curves and crosswinds. That means a calmer drive where you're less tired after long trips.
Long highway drives can become tiring when your vehicle leans through curves or gets pushed around by crosswinds and passing traffic. This rear anti-sway bar helps reduce body roll, improve tracking, and increase cornering control so your suspension feels more planted through changing road conditions. Its thicker diameter than many factory sway bars increases torsional roll stiffness, helping your vehicle settle more quickly after weight shifts and making long trips feel calmer behind the wheel.
Handling improvements depend on more than adding a replacement bar. This anti-sway bar uses 4140 chromoly steel to increase strength and durability, while polyurethane bushings resist gas, oil, ozone, abrasion, and heavy loads better than standard rubber bushings. Those design choices help your suspension maintain consistent roll control through curves, uneven pavement, and changing road conditions, keeping your vehicle composed as the miles add up.
Suspension components spend their lives exposed to road debris and the elements, so lasting protection matters. A powder-coated finish helps resist wear and corrosion while the custom-fit design integrates with your suspension system to improve overall handling. Your anti-sway bar continues delivering predictable roll control trip after trip, helping your vehicle retain the same planted feel throughout years of service.

Hi, everybody. Andy here with etrailer. Let's take a quick look at this Roadmaster rear anti-sway bar. Now this bar has been designed to feature 2020 to current Ford Transit T350. And on custom fit parts such as this bar, I do recommend taking advantage of our vehicle fit guide here at etrailer. Just input the year, make, and model of your vehicle, and our fit guide will confirm if this will work for you or if we have something comparable that will work for you.
Now this anti-sway bar is designed to make your vehicle feel more stable and controlled on the road. It's gonna help reduce that body roll so that your vehicle is going to stay flatter when you're going through those curvy roads, dealing with crosswinds, or traveling on uneven roads. That added stability is also going to improve tracking on the highway, meaning you shouldn't have to make as many steering corrections to help keep your vehicle going where you want. Now a big part of that improvement comes from this sway bar's thicker diameter, which is going to give you greater resistance to twisting than many factory sway bars. So the result again is gonna be a more planted, confident feel while you're behind the wheel.
This is also built to handle demanding use. This sway bar is made from strong 4140 chromoly steel to give you consistent suspension performance even under those heavier loads. The bushings here are polyurethane, so they're designed to stand up to oil, gas, ozone, abrasion, and load-resistant wear. And then our bar itself and the end links here, they are covered with a black powder coat finish to help to protect them from corrosion and everyday wear. It includes everything that you see here.
Overall, it's gonna be a solid upgrade if you're looking to reduce body roll, improve highway stability, and make your vehicle feel more controlled and predictable while you are traveling. I'm looking at the instructions here. The diameter of this bar is gonna be 1 1/2 inches. So again, 1 1/2 inches. If you are wondering about installation, maybe you're not too excited to do it yourself, that's okay because on this product page underneath the photos section, we have a link that will take you to our installer locator.
Click that link, answer the questions that it has for you, and that locator will find an installer in your area that etrailer has partnered with to install this for you. Well, again, my name's Andy. Thank you for joining me.
Ratings & Reviews
Excellent product, easy to install, definitely an upgrade from the oem. Removed the factory stabilizer and installed the roadmaster bar by myself in less than 2 hours. Installed on my 2023 Ram 2500HD.
I submistted a review for both front and rear kits. Both etrailer and Roadmaster are great companies to purchase products. Roadmaster made custom parts and sent them within days.
What an unbelievable difference on my Fleetwood Class A Motorhome. Paired it with a new Rear anti sway bar and 4 new Koni EVO shocks. The handleing and steering are much improved and no more tail wagging in heavy winds, much more enjoyable to drive and no driver fatigue after long driving days.
The product is great! All the other positive reviews of the product are accurate. However, the instructions were not for my vehicle and required a phone call for clarification. Waited about 10 mins on hold to talk to someone but this was on a Sunday so I was surprised that anyone answered. Good job on that. I purchased this item because the ad said no drilling. Step 3 in the instructions was to drill. I passed this on to the folks at etrailer and they agreed this was incorrect and offered a free return to correct the issue. As of 23 May 26 the ad has not been corrected so beware. I needed the item so it went from something I was going to install to something I needed to get installed. Finding an installer for an aftermarket part that requires drilling into your vehicle and wasn't sold by the installer was far more difficult than I thought it would be. Thankfully the guys at my local Air Force base auto hobby shop were up for the task and did a great job. Of course there is additional cost. 3 x $40 an hr for my time trying to install myself, reinstalling original gear, finding an installer and logistics of getting vehicle to and from shop. People dont generally value there time accurately. If you had to take time off work 1hr x $40 which I did should also be calculated. With the installer fees this amounted to an additional $380. That's additional cost to me because of a poorly advertised item. This is the part that bugs me about etrailer. They were very friendly on the phone and tried to be helpful with the instructions but other than returning the item, didn't offer a discount for the added frustration or even a coupon for a future purchase. This of course is not required of them but for a purchase as expensive as this you might think this would be a no brainer. I think they could do better.
I have carried a truck camper for 7 years with just Timbrin blocks also from Etrailer and finally made the move to Roadmaster anti sway bars front and rear. Planning a trip to the west coast from Georgia next year and wanted all the help I can get for stability on the mountain roads. Have yet to test but Im sure it will be a noticeable improvement. When my wife takes the wheel so I can have a break she would see-saw the steering wheel to balance the load and it drove me insane. Hoping for relief for both of us.
We were told this sway bar might not work on our Dodge Ram3500 dually. Let me tell you this worked great. Our truck has a camper on top and we took this on a long trip and it worked great. What a difference it made. This trip had lots of very high winds. We could easily tell the difference from before the sway bar and after. Thanks
As others have said the sway bar is good but the directions could be improved. Removing the old down link on the drivers side is a bit of a challenge as you can't easily remove the old bracket until you remove the downlink. Unfortunately you can't get the bolt holding the link to the bracket without supporting the fuel tank and removing the rear strap so that you can push the tank over far enough to get the bolt out. Another issue was the old U brackets holding up the old sway bar were on 3" centers where the new bracket is on 2 3/4" centers. This looks like an insurmountable problem until you remove the star washers holding the old bolts where you can see there is a slot which allows you to use the bolts included. The old bolts were both attached to a plate which kept made the center distance between the bolts non adjustable so using the old bolts is not an option. On the passenger side the plate holding the 2 bolts was connected to the axle connection for the height sensing proportioning valve. I removed the 3 bolts holding it, took out the plate and cut off the front most bolt and reinstalled the plate. Fortunately that allowed me to use the old bolt in the plate and for the front most bolt I used one from the kit and achieved the 2 3/4" center spacing needed for the new bracket. All of this would be nice to know when you tackle this job. Fortunately I had all the tools needed to complete the job. I found it easy to install the new bar despite its weight by lifting up one end of the sway bar and loosely attaching it to the the down link. I then did the other side and once both ends were attached I put the center of the bar on my hydraulic jack and lifted it into place. This made it a fairly easy job to position and attach the U brackets to the axle despite the heavy weight of the bar. A video of this process on an older (1998 vintage) Dodge Ram 2500 would be a big help.
Easy to install by myself in the driveway. I replaced both the front and rear anti-sway bars and the improved handling characteristics were noticeable immediately. Fantastic product!
I have a hard side slide in camper in the back of my pickup. This is the first time I installed an Anti-Sway Bar of any kind. It took me about 6 hours to install. But it works, and it works really well. I'm glad I took the time to install it.
1 of the best purchased I've made for my Fleetwood Discovery. All wandering is now gone. Took an afternoon to install (I'm a retired mechanic) and am very pleased with the outcome. I also purchased an Steering Stabilizer Shock a year before and I improved wandering maybe %25. Both purchases arrived (in Alaska) promptly and in good condition. I Will purchase from eTrailer.com again when needed.
I love this sway bar, and love the service and overall experience with etrailer. My F350 came with factory sway bars front and rear, and I'd replaced the rear bar several years ago, and was impressed with the difference it made. So, more recently I ordered the front bar to replace the smaller factory unit, and it again made a wonderful change for the better. Our Bigfoot truck camper is tall and heavy, but our rig handles wonderfully and has essentially no sway or rock in traffic or on bumpy roads. I highly recommend this sway bar.
Easy installation ,done by myself laying on my back in the driveway only took about 1 1/2 hours to do. I have a lift but didn't use it and I think it was easier on the ground for just one person. Sway bar made a big difference in the drivability of my 2003 E350 pleasure way class B
I'll upgrade the front factory bar to the HD Roadmaster bar soon
If you have issues with the handling of your Ford pleasure way start with this sway bar
After a year of usage, I couldn't be happier with the Roadmaster front and rear anti-sway bar kits. The rear kit for my W22 chassy, the mounting hardward would not fit properly. I call Roadmaster directly and they custom built the mounts, painted, and shipped within days.
I Installed the bar in my Ram promaster HR 2500 and it’s an incredible difference on twisty mountain roads. I highly recommend it.
After waiting 3 weeks the swaybar kit was drop-shipped from the factory. Received and discovered the bushing inserts were the wrong size (too small) for the bolts that were sent. Contacted Roadmaster support and provided them a photo and invoice as requested. The replacement inserts were approved and shipped out. I got metric bolts to go with the inserts I received. I will save the replacements for additional replacements.
The install was fairly straight forward.
Haven't had a chance to tow the 5th-wheel yet.
a quick fix it to install sway bars front and rear.
I did this and just came home from 2400 mile trip.
installed rear only before we left, then at our destination installed front.
the drive back it handles wayyy better and it sits level now.
""your results may very-use at your own risk. ""
from etrailer.com
rear = RoadMaster 1259-109.
front = RoadMaster RM-1259-105 with RM-590063-00 bracket kit.
i'm sure over time they will flex and stress and start to lien again.
But for now it looks much happier. ( and level )
and i'm very happier with performance and drivability
Seems the big bars help distribute the load to both sides,
you can drive it with one hand now.
and when a truck passes, it's very manageable.
( this could be part the tires on it )
these can be installed in about 6 hours pretty easy.
The hardest thing is drilling the 8 holes in frame. ( 4 front 4 rear. )
We had to shift 2 brake lines over via and small bracket and covers lines with old fuel like to act as wear buffer.
The anti sway bar is a big improvement when the truck bed camper is on. The installation took a bit longer than expected because the frame brackets don’t fit around an aftermarket B&W gooseneck hitch. I had to fabricate new top brackets and drill out the bottom brackets to widen the bolt pattern. Keep this in mind if you have a gooseneck hitch.
Received the product in a timely manner. The shipping company used I’d give a no star rating. I received the anti-sway bar bare out of a box or wrapper with the installation part box and a cut out piece of cardboard with the shipping label on it taped to the bare bar with about five yards of packing tape. The bar was scuffed, scratched and chipped with the RoadMaster label destroyed. I realize it’s going to be installed under the front of my motorhome but as much as it costed I would like to be the one to scratch and scuff it. If I was a company installing this on a customers vehicle I’d return it. I do not believe it was shipped from etrailer in this condition.
Great buying experience with ETrailer. Fast shipping and quality constructed part. Noticeable difference in controlling body sway. Very pleased with the bar and highly recommend Etrailer.
After about a year with both the Roadmaster Rear Anti-Sway Bar and the TorkLift StableLoad Upper Overload Spring Upgrade on our truck camper setup, my experience has been mixed.
With the StableLoads, some of the mounting screws eventually fell out. I contacted etrailer expecting the issue to be handled under warranty, but instead of taking care of the replacement directly, I was referred to the manufacturer. Considering the age of the product and that it was purchased through etrailer, I was disappointed with how the warranty issue was handled.
As for the Roadmaster 1-1/2" rear anti-sway bar, it is a very solid and well-built product, but in our particular application I honestly haven't noticed a major difference in body roll while taking turns with the camper loaded. I have driven the truck both with and without it, and the improvement was much less noticeable than I expected.
Neither product is necessarily bad, but based on our experience, the improvement in handling hasn't been significant enough for me to strongly recommend them given the cost.
2025 Sprinter 2500 low roof WITH factory sway bar. Added this bar to control the terrible handling at the rear of these vans and it absolutely takes care of that. Be aware that you 100% need the retro-fit kit for this bar to be installed as the factory sway bar end links will NOT work. The retrofit kit that you need is the RM-590064-00.
RM-1109-121 Rear Sway bar for 85 Chevyvan G30 RV. Install was pretty straightforward. I would mount the brackets to the frame first and then the sway bar to the axle. It’s easier to drill the holes without the sway bar getting in the way.
Before I replaced the shocks and upgraded the from sway bar and added the rear sway bar my G30 Chevyvan Winnebago was a wallow wagon. It took 110% focus to drive. Now it drives like a regular vehicle. Smooth. No leaning over when cornering. It’s night and day.
Excellent high quality product made a big difference in handling with heavy Artic Fox camper
Give poor rating regarding installation instructions
Great instructions and nice, high quality fasteners.
Fitment was great and only minor adjustments to my Air lift air bags was needed.
I have a 2013 Ram 3500 Dually with:
-Torklift 30K hitch
-5” Exhaust
-Air lift 7500XL air bags.
The lower brackets for the air bags needed to be moved slightly and I had to cut the excess bolt off on the passenger side.
Super quality product build. However it is made for ford transit dually. I have single rear tires. Worked with road master rep to select the correct sway bar for my van.. RM82EQ
